The sleeves are ifixe'd upon the ends o-Qfithe barrels -1 9 and 20. The latter are preferablygiormed from glassoriother suitable transparent ma: terial. The opposite ends of the barrels-are provided with caps; 21 and -22. Each of the barrels is provided with-a filler pgrtipnflg. The reaps '21 and 22 support the. outer ends ofithe barrels :19 and Within therecesses 1 1 and :12, respectively.

plunger -24 is fixed upon the-end of a tubu'lar plunger rod 26. The opposite end of the plunger-rod is fixed witliinan opening {27 in V a valvebody 28., 'flghe valve'tbody-is provided with an opening :29 which {is diametriea'll-y opposed to the opening 27 for receiving ene end of la plunger rod 30. {The end of the plunger rod'30 is rigidly secured Within the opening 29.

- The valve body 28 is provided-wvijzfh a-pair of diametrically-opposed openings31 arid-32. f 'Within which connecting members 33-angl 34,

respectively,are-disposed. An-inlet-=tube 35 I is associated with the {conneeting member 533' and an outlettube 36 is flSSoeiated with the connecting memherBri. The inletltube is prof i ided wane valve sTlhaving' conneting members 3 8fiand 39. A tube .10 is disposed I p n nH P ga emberBS anaa u be-ai iYdiSpos'edfipOn'lthe mber 39; Theitl b in} 40 is -provided with' a hollow needle I42;

Hollow needles such as this are well known in the art and theretorerequire no detailed description. The valve 37 is provided witha handle 43 whereby the valve may be manipulated for placing the tube in communication with the tube 35 01' the latter with the tube 41. The purpose of this construction will bedefined more fully later.

In Figure 2 I have also shown the tube 36 l as being provided with a valve 44. This valve is provlded with connecting members 45 and 46 for receiving tubes 47 and 48, re,

Spectively. The tube 47 is provided with a hollow needle 49. The tube 36 may be placed in communication with the tube 47 or" the tube 48 by manipulating the handle 50 associated with the valve 44., The base plate 1 is provided with a pair of guide members .51 and 52 between which the lower end of the valve body 28 is disposed.

Referring now to Figure 4, it will be noted that the valve body isprovided with a rotatable member 53 having grooves 54 and 55 therein. The inner end of the member 53 is provided with an opening within which a threaded shank 56 associated with a disc 57 is disposed. The inner end of the member 53 is also provided with a rectangular proj ection 58 which is preferably disposedwith in a similar opening in a washer 59. The disc 57 is provided with a plurality of openings between which ball bearings 60 are placed. It will thus be seen that the washer From the foregoing description of the various parts of the device, the operation thereof may be readily understood. Y Preparatory. to making a blood transfusion, let us say that the needle 42 is inserted into a vein in the body of the donor and that the needle 49 is similarly insertedinto a vein in the body ofthe recipient. At this time the valves 37 and 44 are arranged in the positions shown in full lines. Let us assume that the handle 62 is positioned for operation upon the side of the device shown in Figure 5. In operation, the handle is grasped and moved, let us say, from right to lettas viewed in Figure 5, at which time the member 53 will be moved sufficiently far to bring the groove 54 into a position for placing the tube 35 and the plunger rod 26 into "communication. The valve body 28 is provided with a recess'64 whereby a pin-65 which is secured to the member 53 will engage a shoulder 66 or 67 for limiting the distance through which the member 53 is rotated.

When the handle is moved from right to left, the first result is a rotation of the member 53, after which the member 53 is locked against rotation, and continued pressure from right to left upon the handle will cause a movement of the plungers 24 and 25. Such movement will cause blood to flow into the barrel 19 by reason oi the suction created therein. When the. plungers have been moved their entire distance, the handle 62 is moved from left to right, which results in the, member 53'being moved for placing the grooves 54 and 55 in a position shown in Figure 2. Thus it will be seen that the blood within the barrel 19 will be forcedtherefrom into the tube 36 and finally through the needle 49. Simultaneously, the. barrel 20 will be filled with blood which, upon reversing the movement of the plungers, will be forced 'through the tube 36 and the needle 49. By

reason of this construction I have provided a device in whichthe blood to the recipient is caused to flow continuously.

@I .have foundthat one of the greatest obstacles to .making successful blood transfw sions is the coagulation of the blood due to inactivity of the latter during certain stages of the transfusion, Frequently, it becomes necessary to pass a certain amount of solution such as saline to, let us say, the recipient. At this time the valve 37 is moved for bringing the handle from. the full line position to the dcttedline position. This will place the tube 41 in communication with the tube 35 and will cut off the communication between the tube40 and the tube 35. A continued reciprocation of the plungers will cause saline to flow to the recipient. The tube 41 maybe inserted in any suitable receptacle containing saline.

' A further important feature in connect-ion with my invention is the fact that the handle 62 may be reversed. In'other words, it may be operated from both sides of the device; When the handle is manipulated from the lower side shown in Figures 2 and 5, the

direction of flow will be reversed. In many cases it is desirable to pass saline to the donor. Under such conditions, the valve 44 is manipulateclfor placing the tube 48 in communication with the tube 36. Continued manipulation of the handle will cause a flow of the liquid to the donor.

The device may be easily and quickly disassembled by merely loosening the thumb screw8 and moving the member 5 slightly away from the barrel 20. At this time both barrels may be lifted from their supporting members and, by unscrewing the caps 16 and 17, the plungers may be pulled from the barrels. The handle 62 serves a double function in that it reverses the member 53 and at the same time serves as .a grasping element be rigidlysecured upon.
